An elastic arm part is provided on an outer periphery of a cylinder part of a cap, and a projection is formed in an outer periphery of an opening part. When the cap is loosened, the arm part engages the projection and is elastically deformed and after releasing the engagement of the arm part and the projection, an engagement between a first screw part and a second screw part is released. Even if an engaging distance between a first screw part and a second screw part is short, the cap is prevented from rapidly opening, and it is possible to lengthen a time a fuel steam is slowly discharged from the opening part.
